An explanation of how Campbell's "monomyth" is used in advertising and branding:

Joseph Campbell

Campbell was an American mythologist, writer and lecturer, best known for his work in comparative mythology and comparative religion. His work is vast, covering many aspects of the human experience. His philosophy is often summarized by his phrase: "Follow your bliss."

As a strong believer in the unity of human consciousness and its poetic expression through mythology, through the monomyth concept Campbell expressed the idea that the whole of the human race could be seen as reciting a single story of great spiritual importance.

In the preface to The Hero with a Thousand Faces he indicated it was his goal to demonstrate similarities between Eastern and Western religions.

As time evolves, this story gets broken down into local forms, taking on different guises (masks), depending on the necessities and social structure of the culture that interprets it. Its ultimate meaning relates to humanity's search for the same basic, unknown force from which everything came, within which everything currently exists, and into which everything will return and is considered to be "unknowable" because it existed before words and knowledge. NOTE: Noumenal realm.

The Story's form, however, has a known structure, which can be classified into the various stages of a hero's adventures like the Call to Adventure, Receiving Supernatural Aid, Meeting with the Goddess/Atonement with the Father and Return.

As the ultimate truth cannot be expressed in plain words, spiritual rituals and stories refer to it through the use of "metaphors", a term Campbell used heavily and insisted on its proper meaning: In contrast with comparisons, which use the word like, metaphors pretend to a literal interpretation of what they are referring to, as in the sentence "Jesus is the Son of God" rather than "the relationship of man to God is like that of a son to a father".

According to Campbell, the Genesis myth from the Bible ought not be taken as a literal description of historical events happening in our current understanding of time and space, but as a metaphor for the rise of man's cognitive consciousness as it evolved from a prior animal state.


The purposes of mythology according to Campbell:
The Metaphysical Function: Awakening a sense of awe before the mystery of being

According to Campbell, the absolute mysteries of life cannot be captured directly in words or images. Myths are "being statements" and the experience of this mystery can be had only through a participation in mythic rituals or the contemplation of mythic symbols that point beyond themselves.

"Mythological symbols touch and exhilarate centers of life beyond the reach of reason and coercion.... The first function of mythology is to reconcile waking consciousness to the mysterium tremendum et fascinans of this universe as it is."


The Cosmological Function: Explaining the shape of the universe

Myth also functions as a proto-science, bringing the observable (physical) world into accord with the metaphysical and psychological meanings rendered by the other functions of mythology. Campbell noticed that the modern dilemma between science and religion on matters of truth is actually between science of the ancient world and that of today.


The Sociological Function: Validate and support the existing social order, or undermine it

Ancient societies had to conform to an existing social order if they were to survive at all. This is because they evolved under "pressure" from necessities much more intense than the ones encountered in our modern world. Mythology confirmed that order and enforced it by reflecting it into the stories themselves, often describing how the order arrived from divine intervention.

However, in the modern world, a person following his or her Hero's Journey may be forced by duty to go against the existing order and change it, or change parts of it - such as Huck Finn, who had to oppose the slavery embraced by his relatives, or in real life, Edward Snowden and Julian Assange, who sacrificed their freedom to expose the human rights violations of the national security state.


From Joseph Campbell in Elephant Journal:

“The world without spirit is a wasteland. People have the notion of saving the world by shifting things around, changing the rules, and who’s on top, and so forth. No, no! Any world is a valid world if it’s alive. The thing to do is to bring life to it, and the only way to do that is to find in your own case where the life is and become alive yourself.” (Compare Nietzsche.)

“It reminded me of an old parable I’ve heard many times. A young man wants to create change, so he sets out to change the world. After a few years, he finds he has made little progress, so he focuses on changing his country. By the time he is middle-aged, he realizes he must first change his town. And by the time he is an old man, he realizes that he must first focus on changing himself.”


The Psychological Function: Guide the individual through the stages of life

As a person goes through life, many psychological challenges will be encountered. Myth may serve as a guide for successful passage through the stages of one's life. For example, most ancient cultures used rites of passage as a youth passed to the adult stage. Later on, a living mythology taught the same person to let go of material possessions and earthly plans as they prepared to die.

Campbell believed that if myths are to continue to fulfill their vital functions in our modern world, they must continually transform and evolve, because the older mythologies, untransformed, simply do not address the realities of contemporary life, particularly with regard to the changing cosmological and sociological realities of each new era.
